Topdressing zoysia

I have measured the dips randomly and it looks like max deviations are 1" Could I just topdress with sand 1/4"
let it grow through then repeat until level?

I have a cust that is a retired Golf Course super he is a bit nutty but he knows his stuff. I could consult him and let him supervise (he is bored and would love it) or is it simple enough to do myself?

Oh...I cant make ANY mistakes, its a great account and I take care of this guys commercial accounts and his rentals.

I am a strong believer in luck and I find the harder I work the more I have of it.

You could probably do the full 1/4"-1" with a mix of loam and sand and then place some sprigs with good stolon development in the deepest topdressed areas for good measure. We don't have too much Zoysia here in WV, so maybe I'm not 100% right. A retired golf course super could give you all kinds of information on the native grasses in your area. It's worth getting all the info you can to maintain your best interests with this client.
